RMC’s planning and design professionals understand complex wastewater treatment and permitting issues and identify project alternatives that provide the greatest increase in reliability within available project funding.

Wastewater Treatment Facilities

Novato Sanitary District

The Novato Sanitary District is upgrading its wastewater treatment facilities to increase treatment reliability, improve compliance with regulations, replace aging infrastructure, and accommodate a 7:1 wet weather flow without bypassing. For this $84-million project, the RMC team:

• Completed predesign, preparation of CEQA documents, and funding analyses
• Designed extensive modifications and upgrades to the existing treatment plant, including systems for UV disinfection, odor control, and SCADA control
• Designed program for phased construction so the plant could continue to operate
• Provided engineering services during construction

 

Advanced Treatment Analysis

Los Angeles Department of Water and Power

As part of a comprehensive master plan, RMC developed a Long-Term Concepts Report for the City of Los Angeles which included development of advanced tertiary wastewater treatment layouts to maximize recycled water production at the Hyperion, Los Angeles-Glendale, and Terminal Island treatment plants. In addition to the wastewater treatment layouts, RMC prepared:

• In-depth facility evaluations of existing wastewater treatment infrastructure at all three treatment plants
• Master planning documents detailing design concepts and findings
• Capital costs for the potential expansion of the Hyperion Treatment Plant, the City’s end-of-the-line ocean discharge treatment facility

Main Wastewater Treatment Plant Land Use Master Plan and EIR

East Bay Municipal Utility District

To accommodate future expansion needs, the East Bay Municipal Utilities District acquired 15.9 acres of land adjacent to its Main Wastewater Treatment Plant—located on a 48-acre site in an industrialized area of West Oakland. Finalization of a land use master plan and preparation of a programmatic environmental impact report (EIR) will guide the near-and long-term use of the property. RMC:

• Prepared a Land Use Master Plan, developing a 30-year vision for the plant and site
• Led preparation of a programmatic environmental impact report (EIR)
• Completed a Food Waste Expansion Project-level Negative Declaration
